MP2456  
0.5A, 50V, 1.2MHz  
Step-Down Converter in a TSOT23-6  
DESCRIPTION  
FEATURES  
The MP2456 is a monolithic, step-down, switch-  
mode converter with a built-in power MOSFET.  
It achieves a 0.5A peak-output current over a  
wide input supply range with excellent load and  
0.5A Peak Output Current  
1Ω Internal Power MOSFET  
Capable to Start Up with Big Output  
Capacitor  
Stable with Low-ESR Ceramic Output  
Capacitors  
Up to 90% Efficiency  
0.1μA Shutdown Mode  
Fixed 1.2MHz Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over-Current Protection  
Wide 4.5V-to-50V Operating Input Range  
Output Adjustable from 0.81V to 0.9xVIN  
Available in a TSOT23-6 Package  
line  
regulation.  
Current-mode  
operation  
provides a fast transient response and eases  
loop stabilization. Fault condition protections  
include cycle•by•cycle current limiting and thermal  
shutdown.  
The MP2456 requires a minimal number of  
readily-available external components. The  
MP2456 is available in a TSOT23-6 package.  
APPLICATIONS  
Power Meters  
Distributed Power Systems  
Battery Chargers  
Pre-Regulator for Linear Regulators  
WLED Drivers
